2 | ||
3 | Changes between versions 0.4b23 and 0.4b24 (released ?????????????) | |
4 | =================================================================== | |
5 | ||
6 | 1. Fixed the permissions of a newly created QFA file by dump. | |
7 | ||
8 | 2. Cleaned up the source of dump (the external variables | |
9 | definition was a complete mess, making possible to have | |
10 | objects overlap). | |
11 | ||
12 | 3. Fixed restore to use the full tape volume path when doing | |
13 | a compare (since it changes the working directory to the | |
14 | filesystem being compared in the process). | |
15 | ||
16 | 4. Added the -q option to dump which makes dump abort | |
17 | whenever it needs operator attention. It should be | |
18 | easier to use dump in scripts with this option. | |
19 | ||
20 | Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001) | |
21 | =================================================================== | |
22 | ||
23 | 1. Fixed a buffer overflow in restore/tape.c. Patch provided by | |
24 | Marcus Meissner (Caldera International Security Dept.). | |
25 | ||
26 | 2. Implement the Sun rmt extended protocol. Patch submitted | |
27 | by Ian Gordon <iangordon@users.sourceforge.net>. | |
28 | ||
29 | 3. Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of | |
30 | the linux kernel header. This ensures that dump always has the | |
31 | latest version of this file. Patch submitted by | |
32 | Andreas Dilger <adilger@turbolinux.com>. | |
33 | ||
34 | 4. Report any filesystem present in either /etc/fstab with a | |
35 | positive passno or /etc/dumpdates in dump -w output. | |
36 | Patch submitted by Andreas Dilger <adilger@turbolinux.com>. | |
37 | ||
38 | 5. Fixed the looping problem in dump introduced in the | |
39 | previous version. | |
40 | ||
41 | 6. Changed the -B option of dump to limit the size of | |
42 | _compressed_ output per volume if compression is on. | |
43 | Patch contributed by Helmut Jarausch | |
44 | <jarausch@igpm.rwth-aachen.de>. Note however that, since | |
45 | it is impossible to predict the size of the compressed | |
46 | data before doing the compression, the -B limit is a bit | |
47 | conservative. | |
48 | ||
49 | 7. Fixed a bug in reading the operator typed file/tape path for | |
50 | the next volume in restore. | |
51 | ||
52 | 8. Implemented a "-F script" option to restore which permits the | |
53 | user to specify a script which will be launched at the | |
54 | beginning of each tape, useful for automatic programming of | |
55 | tape changers for example. See the restore man page for the | |
56 | script parameters and return codes. | |
57 | ||
58 | 9. Small fix for the QFA routines provided by Uwe Gohlke | |
59 | <uwe@ugsoft.de>, and some recommendations for QFA uses in | |
60 | the man pages. | |
61 | ||
62 | 10. Fixed the multivolume restoring where making a mistake | |
63 | to the 'Mount next tape' prompt caused several blocks to | |
64 | be lost. | |
65 | ||
66 | 11. Enhanced the -e option of dump to take as a parameter a | |
67 | comma separated list of inode numbers. | |
68 | ||
69 | 12. Added the -E option to dump which specify a file containing | |
70 | inode numbers to exclude from the dump. | |
71 | ||
72 | 13. Fixed the compressed multi-volume dump + restore. | |
73 | ||
74 | Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001) | |
75 | ================================================================== | |
76 | ||
77 | 1. Made dump report the number of blocks dumped per volume. | |
78 | Thanks to Kenneth Porter <shiva@well.com> for the suggestion. | |
79 | ||
80 | 2. Fix a bug in dump where waiting too much at the 'change volumes' | |
81 | question caused the volume to be rewritten. Thanks to | |
82 | Graham Reed <greed@users.sourceforge.net> for reporting the | |
83 | bug and providing a patch. | |
84 | ||
85 | 3. Added a compression option to dump, contributed by Jerry | |
86 | Peters <gapeters@worldnet.att.net>. | |
87 | ||
88 | WARNING: the compression works only on files/pipes and | |
89 | drives supporting variable block size. | |
90 | ||
91 | WARNING2: tapes created using the compression feature are | |
92 | incompatible with the standard dump tape format, and a | |
93 | version of restore >= 0.4b22 will be needed for extraction. | |
94 | ||
95 | 4. Fixed some compilation problems for glibc 2.2.2 and 64 bit | |
96 | architectures. Thanks to Paul Slootman <paul@debian.org> for | |
97 | the patch and to Bdale Garbee <bdale@gag.com> for forwarding | |
98 | it upstream. | |
99 | ||
100 | 5. Many cleanups (CPP defines, const char warnings, check of | |
101 | ext2fs COMPAT flags, time_t cleanups, added libext2 version | |
102 | in dump usage text) by Andreas Dilger <adilger@turbolinux.com>. | |
103 | ||
104 | 6. Made --prefix option work in configure. All the install path | |
105 | are now based on the configure parameters. | |
106 | ||
107 | 7. Added the Quick File Access mode in dump/restore, contributed | |
108 | by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in | |
109 | a file tape position for each inode, and this file is used by | |
110 | restore (if called with parameter Q and the filename) | |
111 | to directly position the tape at the file restore is currently | |
112 | working on. This saves hours when restoring single files from | |
113 | large backups, saves the tapes and the drive's head. Use | |
114 | --enable-qfa option of configure to compile in the QFA support. | |
115 | ||
116 | 8. Added the possibility to dump several files and directories | |
117 | in a single invocation of dump. Thanks to Uwe Gohlke | |
118 | <uwe@ugsoft.de> for implementing this option. | |
119 | ||
120 | 9. Fixed the dumping and restoring of files with holes | |
121 | (files ending with holes didn't get dumped or restored | |
122 | correctly). | |
123 | ||
124 | 10. Fixed a socket descriptor leak in dump, which leaved opened | |
125 | 3 file descriptors per dump process (and there is one dump | |
126 | process per tape). | |
127 | ||
128 | 11. Fixed dump large file system support, by explicit use of | |
129 | open64/lseek64/etc functions (explicit use needed because | |
130 | e2fsprogs libraries don't behave well when compiled with | |
131 | FILE_OFFSET_BITS=64). | |
132 | ||
133 | Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001) | |
134 | ====================================================================== | |
135 | ||
136 | 1. Fixed some bugs in the dump -w|-W logic introduced by | |
137 | the previous version. Thanks to Andreas Dilger | |
138 | <adilger@turbolinux.com> for his help on this one. | |
139 | ||
140 | 2. Fixed again a compilation problem when using old e2fs | |
141 | headers (filesystem label related). Thanks to many users | |
142 | who reported this stupid error. | |
143 | ||
144 | 3. Fixed a build problem on old lib5 based systems dealing with | |
145 | _PATH_MNTTAB being undefined. Thanks to John Adams | |
146 | <johna@onevista.com> for reporting the bug. | |
147 | ||
148 | 4. Improved the error detection in restore when creating | |
149 | the temporary files in TMPDIR. Now restore will corectly | |
150 | report a 'no space left on device' error instead of | |
151 | strange errors which could imply an archive corruption. | |
152 | Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and | |
153 | bgjenero <bgjenero@sympatico.ca> for reporting the bug. | |
154 | ||
155 | 5. Added the throughput information in dump's progression | |
156 | messages. Thanks to Andreas Dilger <adilger@turbolinux.com> | |
157 | for the patch. | |
158 | ||
159 | 6. Use libext2fs's inode scanning routines, which are particularly | |
160 | robust when dealing with errors (especially when having some | |
161 | bad blocks on the filesystem). Many thanks to Colin | |
162 | <colin@horizon.com> for reporting the bug, investigating | |
163 | the issues, finding a workaround, writing the patch and | |
164 | fully testing it... (of course, if this patch will break | |
165 | anything, he is to blame for :-)). | |
166 | ||
167 | 7. Made dump and restore LFS aware. Dump can dump a filesystem | |
168 | containing large files, generate a large file on output and | |
169 | restore can restore them. This feature is not enabled by | |
170 | default, use --enable-largefile option of configure to enable | |
171 | it (you need to have a LFS aware glibc though). Thanks to | |
172 | Andrea Arcangeli <andrea@suse.de> for submitting the patch, | |
173 | and to Theodore T'so <tytso@valinux.com> for his always | |
174 | useful thoughts. | |
175 | ||
176 | 8. Made dump ask upon a tape write error if it should rewrite | |
177 | the current volume (assume this is a bad tape) or if it should | |
178 | assume an end-of-tape condition (useful for tape drives which | |
179 | behaves badly at the end of the tape). Thanks to Andreas | |
180 | Dilger <adilger@turbolinux.com> for the suggestion. | |
181 | ||
182 | Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000) | |
183 | ======================================================================= | |
184 | ||
185 | 1. Fixed a small compilation problem due to a change | |
186 | in the definintion of the struct sigaction in | |
187 | glibc 2.0 / libc5. Thanks to Gunther Schlegel | |
188 | <schlegel@riege.de> for reporting the bug and to | |
189 | Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting | |
190 | a fix. | |
191 | ||
192 | 2. Modified the label and uuid analysis in order to be | |
193 | self-contained (independant of kernel/libc headers). This | |
194 | should fix the compile with older kernel/libc headers and | |
195 | will preserve the functionality. Thanks to Bernhard Erdmann | |
196 | <bernhard.erdmann@gmx.de> for reporting the bug. | |
197 | ||
198 | 3. The 'exclude inode' option, if applied to a directory | |
199 | inode, excludes now correctly all the leaves of this | |
200 | directory. Thanks to John R. Dennison | |
201 | <gerdesas@users.sourceforge.net> for reporting the bug. | |
202 | ||
203 | 4. Fixed the '-e' option to disable the possibility | |
204 | to exclude the root inode (which causes the dumps to | |
205 | be unreadable by restore). Prevented array overflow | |
206 | when multiple -e options are used. | |
207 | ||
208 | 5. Fixed dump to correctly interpret a filesystem argument | |
209 | which is a mountpoint and it is not an absolute path | |
210 | (as specified in the fstab). Thanks to Bernhard R. Erdmann | |
211 | <be@berdmann.de> for reporting the bug. | |
212 | ||
213 | 6. Made dump able to backup files larger than 2 GB. Note that | |
214 | dump still doesn't cope with files larger than 4 GB. | |
215 | ||
216 | 7. Restore the real uid and gid before invoking an external | |
217 | RSH program (big hole when dump or restore is suid root!). | |
218 | ||
219 | 8. Get the values for the default tape device and the location | |
220 | of fstab file from the system headers. Thanks to | |
221 | Andreas Dilger <adilger@turbolinux.com> for the patch. | |
222 | ||
223 | 9. Made dump -w|-W report all recognized filesystems | |
224 | present in either /etc/fstab or /etc/dumpdates, and present | |
225 | the list in the same order as in fstab file. Thanks | |
226 | to Andreas Dilger <adilger@turbolinux.com> for the patch. | |
227 | ||
228 | 10. Made dump's -a (automatic end of tape detection) the | |
229 | default. Specifying one of -B, -c, -d or -s options will | |
230 | override the EOM detection. Thanks to Andreas Dilger | |
231 | <adilger@turbolinux.com> for the patch. | |
232 | ||
233 | 11. Save the ext2 filesystem label into the dump volume label. | |
234 | Specifying a volume label on the command line (-L option) | |
235 | will override this feature. Thanks to Andreas Dilger | |
236 | <adilger@turbolinux.com> for the patch. | |
237 | ||
238 | Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000) | |
239 | ===================================================================== | |
240 | ||
241 | 1. Fixed the signal handling in dump (which I broke in 0.4b17) | |
242 | which was causing several strange dump failures (dump | |
243 | hanged or segmentation faults etc). | |
244 | ||
245 | 2. Specified the default blocksize in the dump man page. | |
246 | ||
247 | 3. Changed two info messages of restore to be written on stdout | |
248 | instead of stderr in order to leave stderr only for errors | |
249 | or warnings. Thanks to Stephen Atwell | |
250 | <satwell@urbana.css.mot.com> for the suggestion. | |
251 | ||
252 | 4. Corrected an off by one calculation which prevented | |
253 | dumping a directory having a 1 character name length. | |
254 | Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de> | |
255 | for reporting the bug. | |
256 | ||
257 | 5. Reinforce dump in order to allow only level 0 and no | |
258 | -u option when dumping a subdirectory, and document | |
259 | this in the man page. Thanks to Bernhard Erdmann | |
260 | <bernhard.erdmann@gmx.de> for reporting the bug. | |
261 | ||
262 | 6. Fixed a small harmless bug in restore which caused | |
263 | in some conditions hard links to be restored several | |
264 | times (therefore generation some warning messages). | |
265 | Thanks to Kenneth Porter <shiva@well.com> for | |
266 | reporting the bug. | |
267 | ||
268 | 7. Updated the RPM spec file to the latest RedHat version, | |
269 | providing FHS packaging and other cosmetic changes. | |
270 | You will need RPM version >= 3.0.5 in order to build the RPM. | |
271 | ||
272 | 8. Updated the configure script to check for libtermcap | |
273 | before checking for libreadline, because we need this | |
274 | library in order to compile the readline support. | |
275 | ||
276 | 9. Made dump understand the LABEL= and UUID= notation | |
277 | both in /etc/fstab and on the command line. Note that | |
278 | you will need the /proc filesystem in order to use | |
279 | these notations. Thanks to Erik Troan <ewt@redhat.com> | |
280 | for providing the patch. | |
281 | ||
282 | Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000) | |
283 | =================================================================== | |
284 | ||
285 | 1. Fixed a potential buffer overflow in restore. Thanks | |
286 | to Stan Bubrouski <satan@fastdial.net> for reporting | |
287 | the bug. | |
288 | ||
289 | 2. Fixed a readline-related bug which prevented | |
290 | 'cat DUMPFILE | restore -i -f -' from working. Thanks | |
291 | to Charles Karney <karney@users.sourceforge.net> | |
292 | for the bug report. | |
293 | ||
294 | 3. Changed a few "panic" into "exit", causing restore to | |
295 | be more stable against some attacks (like the last one | |
296 | reported on Bugtraq, although the last version of restore | |
297 | was not vulnerable - just dumped core). Thanks to | |
298 | Andreas Hasenack <andreas@conectiva.com.br> for reporting | |
299 | the bugs to me. | |
300 | ||
301 | 4. Removed the suid-root bit on dump and restore in the | |
302 | default build (and generated RPMs). It should be safer | |
303 | now. Users who need the suid-root capabilities in order | |
304 | to make network backups should read first the man page | |
305 | of dump and enable the suid bit manually. | |
306 | ||
307 | 5. Added -ltermcap to the compile parameters for restore | |
308 | when using readline support, in order to make the compile | |
309 | process work on some systems (SuSE ?). Thanks to | |
310 | Patrik Schindler <poc@pocnet.net> for reporting the bug. | |
311 | ||
312 | Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000) | |
313 | ==================================================================== | |
314 | ||
315 | 1. The -F script is called now *only* at the end of a tape, | |
316 | not at the end of the dump. Thanks to Christian Haul | |
317 | <haul@informatik.tu-darmstadt.de> for the bug report. | |
318 | ||
319 | Normally, the device name and the current volume number | |
320 | are passed on the command line of the script. However, | |
321 | if you want the old style script (with no arguments | |
322 | passed on the command line), you can enable it in | |
323 | configure with the --enable-oldstylefscript. | |
324 | ||
325 | 2. Use posix signal handling to preserve dump functionality | |
326 | with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for | |
327 | the patch. | |
328 | ||
329 | 3. Made the exit code of restore in case of a 'C'ompare | |
330 | command reflect the result of the compare. An exit status | |
331 | of 0 means the dump archive is correct, 1 means tape errors, | |
332 | 2 means that some files were modified. Thanks to Kenneth Porter | |
333 | <shiva@well.com> for the suggestion. | |
334 | ||
335 | 4. Made (finally) quotes work in interactive restore. | |
336 | ||
337 | 5. Small fixes in order to allow dump to compile with a | |
338 | really old e2fsprogs version. Thanks to Ian Zimmerman | |
339 | <itz@speakeasy.org> for the bug report. | |
340 | ||
341 | 6. Add GNU readline capabilities to interactive restore. | |
342 | Use configure's --enable-readline flag to enable this feature. | |
343 | Thanks to Patrik Schindler <poc@pocnet.net> for the | |
344 | suggestion. | |
345 | ||
346 | 7. Do the compare on the fly in restore 'C' mode (this will | |
347 | allow not to exhaust the available /tmp space when | |
348 | ccmparing large files). Thanks to Kenneth Porter | |
349 | <shiva@well.com> for the suggestion. | |
350 | ||
351 | Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000) | |
352 | ==================================================================== | |
353 | ||
354 | 1. Fixed some several duplicate 'DUMP: DUMP:' in the | |
355 | output of dump. | |
356 | ||
357 | 2. Corrected the estimation of blocks to dump. Note that | |
358 | this is still wrong for large directory inodes, due | |
359 | to the size of a BSD directory entry on the tape | |
360 | (estimation is based on the size of the ext2 directory, | |
361 | which is smaller because it doesn't contain the null | |
362 | character at the end). | |
363 | ||
364 | 3. Made dump report the total number of MB written to | |
365 | tape at the end of run. Thanks to W. Reilly Cooley | |
366 | <wcooley@nakedape.cc> for the patch. | |
367 | ||
368 | 4. Added the -X option to restore giving the possibility | |
369 | to read the names of the files to be extracted/listed | |
370 | from a text file (in addition of the command line). | |
371 | Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the | |
372 | patch. | |
373 | ||
374 | 5. Added the device name and the current volume number | |
375 | as arguments to the end of tape script (dump -F option). | |
376 | ||
377 | 6. Made the multi-volume dump work again (after having | |
378 | broken it in 0.4b15). | |
379 | ||
380 | Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000) | |
381 | =================================================================== | |
382 | ||
383 | 1. Added a prompt command in interactive restore mode. Thanks | |
384 | to Andreas Dilger <adilger@home.com> for the patch. | |
385 | ||
386 | 2. Fixed a buffer overflow problem in dump (caused by | |
387 | not checking the size of the filesystem parameter). | |
388 | Thanks to Kim Yong-jun <loveyou@hackerslab.org> for | |
389 | reporting this on Bugtraq (and to several dump users | |
390 | who forwarded me his mail). | |
391 | ||
392 | 3. Added the '-F script' option to dump in order to | |
393 | launch a script at the end of each tape (to be used | |
394 | with a tape changer, or to notify the sysadmin by | |
395 | pager etc.). | |
396 | ||
397 | 4. Fixed a bug in restore compare code caused by the changes | |
398 | I made in 0.4b14. | |
399 | ||
400 | 5. Fixed the treatment of options using the old BSD syntax | |
401 | in both dump and restore. | |
402 | ||
403 | Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000) | |
404 | ======================================================================= | |
405 | ||
406 | 1. Fixed a bug in dump which may have caused invalid deleted | |
407 | directories to be dumped out if they were deleted after the | |
408 | mapping pass. This could occure on active filesystem and lead | |
409 | to heap corruption (causing dump malfunction in many possible ways). | |
410 | Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this | |
411 | bug and submitting the patch. | |
412 | ||
413 | 2. Fixed the handling of the filesystem parameter in dump. A | |
414 | '/mnt/disk' parameter caused the disk contents to be dumped, | |
415 | but a '/mnt/disk/' parameter caused the mountpoint directory | |
416 | to be dumped (generally an empty directory). | |
417 | ||
418 | 3. Improved the output of dump in order to tell which directory | |
419 | it is currently dumping (when dumping a subtree). | |
420 | ||
421 | 4. Added the '-e' exclude inode option to dump. Thanks to | |
422 | Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch. | |
423 | ||
424 | 5. Added a REPORTING-BUGS file in order to provide a guide | |
425 | on how to correctly report a bug in dump/restore. | |
426 | ||
427 | 6. Fixed a restore problem when restoring a hard link to an inode | |
428 | having the immutable or append-only attribute set. Thanks to | |
429 | Ambrose Li <acli@mingpaoxpress.com> for submitting the patch. | |
430 | ||
431 | 7. Fixed a compatibility problem between dumps made on little | |
432 | endian machines (the format was correct) and big endian | |
433 | machines (the format was incorrect). This fix break the | |
434 | compatibility with the older dumps made on big endian | |
435 | machines (sparc, m86k, ppc etc). For the first time in | |
436 | linux dump's history (I believe), the dumps made by *BSD, | |
437 | Linux/alpha, Linux/sparc and Linux/x86 are compatible, | |
438 | so interchangeable. Thanks to Rob Cermak | |
439 | <cermak@ahab.rutgers.edu> for submitting the bug and | |
440 | helping me test the fix. | |
441 | ||
442 | 8. Fixed the way dump reports the remaining percent/time, if | |
443 | the number of blocks actually dumped exceeds the estimated | |
444 | number of blocks. Thanks to Jean-Paul van der Jagt | |
445 | <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug. | |
446 | ||
447 | Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000) | |
448 | ====================================================================== | |
449 | ||
450 | 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski | |
451 | <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug. | |
452 | ||
453 | 2. Removed the requirement to build the RPM as root from the | |
454 | spec file. Thanks to Christian Weisgerber | |
455 | <naddy@mips.rhein-neckar.de> for submitting this. | |
456 | ||
457 | 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs, | |
458 | causing dump to block when dumping really huge filesystems. | |
459 | Many thanks to Patrik Schindler <poc@pocnet.net> for | |
460 | helping me find this bug. | |
461 | ||
462 | 4. Fixed the treatment for an interrupt signal when dump access | |
463 | the remote tape through RSH. Thanks to Christian Weisgerber | |
464 | <naddy@mips.rhein-neckar.de> for providing the patch. | |
465 | ||
466 | 5. Fixed a bug which was causing dump/restore to display | |
467 | garbage characters instead of the remote host name. | |
468 | ||
469 | Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000) | |
470 | ===================================================================== | |
471 | ||
472 | 1. Small fix in the dump man page. Thanks to Thorsten Kukuk | |
473 | <kukuk@suse.de> for submitting the patch. | |
474 | ||
475 | 2. Fix for the exit code when using the size estimate option of | |
476 | dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for | |
477 | submitting the patch. | |
478 | ||
479 | 3. Handle EINTR in atomical reads/writes in dump, which was causing | |
480 | dump to fail on some systems. Thanks to Eric Jergensen | |
481 | <eric@dvns.com> for reporting the bug and submitting the patch. | |
482 | ||
483 | 4. Handle more than 16 characters for the device names in dumpdates. | |
484 | (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for | |
485 | tracking down the problem and proposing the solution. | |
486 | ||
487 | 5. Fixed a bug in dump which prevented the creation of the | |
488 | dumpdates file when doing a 0-level dump without already | |
489 | having a dumpdates file. Thanks to Patrik Schindler | |
490 | <poc@pocnet.net> for reporting the bug. | |
491 | ||
492 | 6. Changed the way dump 'S' flag reports the size estimate | |
493 | from number of blocks into bytes (making it compatible | |
494 | with the Solaris version, and simplifying things for | |
495 | amanda users). Thanks to Jason L Tibbitts III | |
496 | <tibbs@math.uh.edu> for reporting the bug. | |
497 | ||
498 | 7. Fixed a compatibility problem in linux/alpha dump tape format. | |
499 | Now the linux/alpha dump are (again) compatible with the | |
500 | other dump formats. But this breaks compatibility with | |
501 | older dumps made on alpha. Thanks to Mike Tibor | |
502 | <tibor@lib.uaa.alaska.edu> for helping me in finding this bug. | |
503 | ||
504 | Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999) | |
505 | ====================================================================== | |
506 | ||
507 | 1. Added a '--enable-kerberos' to configure. | |
508 | ||
509 | 2. Added a 'S' option to dump which determines the amount of space | |
510 | that is needed to perform the dump without actually doing it, similar | |
511 | to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak | |
512 | <cermak@ahab.rutgers.edu>. | |
513 | ||
514 | 3. Added a 'M' multi-volume option to dump and restore which enables | |
515 | dumping to multiple files (useful when dumping to an ext2 | |
516 | partition to make several dump files in order to bypass the 2GB | |
517 | file size limitation). The 'f' argument is treated as a prefix and | |
518 | the output files will be named <prefix>001, <prefix>002 etc. With | |
519 | the 'M' flag, restore automatically selects the right file without | |
520 | asking to enter a new tape each time. | |
521 | ||
522 | 4. Fixed a memory leak which was causing dump to grow very big | |
523 | (270MB when dumping a 10GB filesystem...). Thanks to Jason | |
524 | Fearon <jasonf@netrider.org.au> for reporting the bug. | |
525 | ||
526 | Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999) | |
527 | ====================================================================== | |
528 | ||
529 | 1. Make configure test if the system glob routines support | |
530 | extended syntax (ALTDIRFUNC). If not, use the internal glob | |
531 | routines instead of system ones. Thanks to Bernhard Sadlowski | |
532 | <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug | |
533 | and helping me resolve this and other minor libc5 compiling | |
534 | glitches. | |
535 | ||
536 | 2. Fix a problem when dumping a ext2fs with the 'filetype' | |
537 | feature enabled. Thanks to Patrick J. LoPresti | |
538 | <patl@cag.lcs.mit.edu> for reporting the bug and to | |
539 | Theodore Y. Ts'o <tytso@mit.edu> for providing the patch. | |
540 | ||
541 | 3. Made the nodump flag work on directories. A directory which | |
542 | has the nodump flag gets never dumped, regardless of its | |
543 | contents. | |
544 | ||
545 | 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org> | |
546 | which allows dump on an active ext3 filesystem. However, this | |
547 | is a "quick and dirty" patch which enables backup of an ext3 | |
548 | filesystem through the ext2 compatibility (by ignoring the | |
549 | NEEDS_RECOVERY bit). The journal file is not recognized and | |
550 | it is dumped (it should not). | |
551 | ||
552 | 5. Test the superblock compatibility flags when dumping, in order | |
553 | to be sure that we know how to deal with specific features. | |
554 | ||
555 | Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999) | |
556 | ==================================================================== | |
557 | ||
558 | 1. Use lchown instead of chown, fixing a possible security problem | |
559 | when restoring symlinks (a malicious user could use this | |
560 | to deliberately corrupt the ownership of important system files). | |
561 | Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting | |
562 | this and providing the patch. | |
563 | ||
564 | Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999) | |
565 | ==================================================================== | |
566 | ||
567 | 1. Put dump sources under CVS, added Id tags in all files so | |
568 | one can use 'ident' on binary files. | |
569 | ||
570 | 2. Added the dump/restore version in the usage text so one can | |
571 | easily verify the version he is using. | |
572 | ||
573 | 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes | |
574 | a va_start/va_end problem on linux-ppc (always call va_start | |
575 | va_end in pairs each time we use a vararg function). | |
576 | ||
577 | 4. Added again the DT_* constants because old libc does not | |
578 | contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr> | |
579 | for submitting the bug report. | |
580 | ||
581 | 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs | |
582 | this should enable dumping big (huge) filesystems. | |
583 | ||
584 | 6. Added the RSH environment variable in order to be able to | |
585 | use a rsh replacement like ssh when doing remote backups (and | |
586 | bypass the security limitations of rcmd). Now you can do remote | |
587 | backups without being root (or making dump setuid root). | |
588 | ||
589 | 7. Modified again the way dumpdates works. For incremental dumps, | |
590 | we need to read dumpdates even if we are not using 'u' option. | |
591 | Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how | |
592 | this should work. | |
593 | ||
594 | Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999) | |
595 | =================================================================== | |
596 | ||
597 | 1. Removed the 'k' flag from the restore 'about' text if kerberos | |
598 | was not compiled in. | |
599 | ||
600 | 2. Prototyped (f)setflags from e2fsprogs and corrected the calls | |
601 | to them (fsetflags takes a char*, setflags an open fd!). | |
602 | ||
603 | 3. (f)setflags is called only if the flags aren't empty. If the | |
604 | file is a special file, a warning is printed, because changing | |
605 | flags implies opening the device. Normally, a special file | |
606 | should not have any flag... (Debian bug #29775, patch provided | |
607 | by Abhijit Dasgupta <abhijit@ans.net>). | |
608 | ||
609 | 4. Made possible to dump a file system not mentioned in /etc/fstab. | |
610 | (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>). | |
611 | ||
612 | 5. Changed the default behaviour to not create dumpdates | |
613 | unless 'u' option is specified. Removed the old "debian-patch" | |
614 | which provided the same thing. (Debian bug #38136, #33818). | |
615 | ||
616 | 6. Removed all those dump*announce, since they were getting old... | |
617 | ||
618 | 7. Added warning messages if dumpdates does not exist and | |
619 | when an inferior level dump does not exist (except for a level 0 | |
620 | dump). | |
621 | ||
622 | 8. Debugged the glob calls in interactive mode: restore used a | |
623 | dirent struct which was different from the /usr/include/dirent.h | |
624 | one (this used to work, is it a glibc2 change?), so none of the | |
625 | compat glob (which used /usr/include/dirent.h) or the system glob | |
626 | worked. Restore use now the system dirent (and the system | |
627 | DT_* constants), which are compatible with BSD ones. | |
628 | ||
629 | 9. Added a configure flag (--with-dumpdatespath) to specify | |
630 | the location of dumpdates file. By default, it is | |
631 | /etc/dumpdates. | |
632 | ||
633 | 10. Added the "AUTHOR" and "AVAILABILITY" sections and | |
634 | included the current date/version in man pages. | |
635 | ||
636 | 11. Corrected the estimation of remaining time when | |
637 | the operator doesn't change the tapes quickly enough. This | |
638 | was an old bug, I thought I corrected it, and discovered | |
639 | that in fact it was corrected in two different places, so | |
640 | the results canceled each other... | |
641 | ||
642 | Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999) | |
643 | =================================================================== | |
644 | ||
645 | 1. Integrated multiple patches from RedHat, Debian and SuSE: | |
646 | ||
647 | - tweak dump/itime.c to not try to read dumpdates if the 'u' option | |
648 | isn't specified. | |
649 | - several fixes in the man pages. | |
650 | - update the default tape device to /dev/st0. | |
651 | - many updates for Linux Alpha (byte ordering, size_t etc). | |
652 | - buffer overruns. | |
653 | - use environment variable for TMPDIR (instead of /tmp). | |
654 | - use sigjmp_buf instead of jmp_buf (RedHat bug #3260). | |
655 | - workaround egcs bug (RedHat bugs #4281 and #2989). | |
656 | - wire $(OPT) throughout Makefile's. | |
657 | ||
658 | 2. Upgrade the dump revision to 1, making possible to dump filesystems | |
659 | made with e2fsprogs-1.15 or newer. Nothing seems to break... | |
660 | ||
661 | 3. Fix some compile warnings, prototype all functions. | |
662 | ||
663 | 4. Use glibc err/glob instead of internal compatibility | |
664 | routines (only if available). | |
665 | ||
666 | 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided | |
667 | by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>). | |
668 | ||
669 | Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999) | |
670 | ====================================================================== | |
671 | ||
672 | 1. Integrated the changes from FreeBSD-3.1-RELEASE | |
673 | (mostly bug fixes, buffer overruns, dump has now an "automatic | |
674 | tape length calculation" flag, dump/restore can use kerberos now | |
675 | (this is NOT tested), use environment variables for TAPE and | |
676 | RMT etc.). | |
677 | ||
678 | 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches) | |
679 | ||
680 | 3. Corrected a bug in restore when using 'C' option with multi-volumes | |
681 | tapes (files splited accros two tapes give "size changed" errors | |
682 | when comparing). | |
683 | ||
684 | 4. Corrected the long standing bug when dumping multiple tapes. | |
685 | This works for me, needs further testing. | |
686 | ||
687 | Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997) | |
688 | ==================================================================== | |
689 | ||
690 | 1. Dump now runs correctly on kernels 2.1.x | |
691 | Fix made by Gerald Peters <gapeters@worldnet.att.net> | |
692 | ||
693 | Changes between versions 0.4b2 and 0.4b3 | |
694 | ======================================== | |
695 | ||
696 | 1. Use realpath() if available | |
697 | ||
698 | 2. Report statistics | |
699 | ||
700 | Changes between versions 0.4b1 and 0.4b2 | |
701 | ======================================== | |
702 | ||
703 | 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating | |
704 | the patch) | |
705 | ||
706 | 2. Fixed restore to make it able to read FreeBSD 2.x dumps again | |
707 | ||
708 | 3. Fixed configure.in to correctly handle --enable-rmt | |
709 | ||
710 | Changes between versions 0.3 and 0.4b1 | |
711 | ====================================== | |
712 | ||
713 | 1. Integrated the changes from 4.4BSD-Lite2 | |
714 | ||
715 | 2. Integrated the patches from Debian and Red Hat | |
716 | ||
717 | 3. Portability changes: use the __u32, __u16, __s32, and __s16 types | |
718 | ||
719 | 4. Changed dump to use the Ext2fs library to get block addresses. This | |
720 | should solve the endianness problem on SparcLinux. | |
721 | ||
722 | 5. Created a configure.in file (shamelessly stolen from the e2fsprogs | |
723 | distribution's one) to use autoconf | |
724 | ||
725 | 6. Fixed a few minor bugs | |
726 | ||
727 | Changes between versions 0.2e and 0.2f | |
728 | ====================================== | |
729 | ||
730 | 1. Added the creation of named pipes (fifos) in restore. | |
731 | ||
732 | 2. Added the -N flag in the restore manual page. | |
733 | ||
734 | 3. Added the file kernel.patch which contains the llseek() optimization | |
735 | patch for 1.2.x kernels. | |
736 | ||
737 | 4. Fixed a bug in the restoration of symbolic links: owner and group were | |
738 | not restored. | |
739 | ||
740 | 5. Integrated some changes from FreeBSD 2.2. | |
741 | ||
742 | 6. Added a call to ftruncate() after restoring each file to restore | |
743 | correctly files ending by a hole. | |
744 | ||
745 | Changes between versions 0.2d and 0.2e | |
746 | ====================================== | |
747 | ||
748 | 1. Fixed a bug in the "set owner/mode" process. Every file was restored | |
749 | with owner = root (0) and group = root/wheel/whatever (0). | |
750 | ||
751 | Changes between versions 0.2c and 0.2d | |
752 | ====================================== | |
753 | ||
754 | 1. Dump is now able to backup 2GB+ filesystems. | |
755 | ||
756 | 2. Dump and restore can now be linked as static binaries. | |
757 | ||
758 | Changes between versions 0.2b and 0.2c | |
759 | ====================================== | |
760 | ||
761 | 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links. | |
762 | ||
763 | Changes between versions 0.2a and 0.2b | |
764 | ====================================== | |
765 | ||
766 | 1. Really fixed the bug that I should have corrected in 0.2a. | |
767 | ||
768 | 2. Enabled optimization again. | |
769 | ||
770 | Changes between versions 0.2 and 0.2a | |
771 | ===================================== | |
772 | ||
773 | 1. Disabled the optimization during compilation. | |
774 | ||
775 | Changes between versions 0.1 and 0.2 | |
776 | ==================================== | |
777 | ||
778 | 1. Fixed a bug in fstab.c which caused a null pointer to be stored in | |
779 | the fs_type field (actually, I modified the file fstab.c to make it | |
780 | use the mntent functions). | |
781 | ||
782 | 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups | |
783 | made by dump should be readable by the BSD restore and backups made | |
784 | by the BSD dump should be readable by restore. Unfortunately, this | |
785 | means that the dump format has changed between version 0.1 and version | |
786 | 0.2 :-( | |
787 | ||
788 | 3. Dump is now able to backup a subtree, it is no longer limited to whole | |
789 | filesystems like the BSD version. | |
790 | ||
791 | 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger | |
792 | than 2 GB. | |
793 | ||
794 | Changes between versions 0.0 and 0.1 | |
795 | ==================================== | |
796 | ||
797 | 1. Now create links rdump and rrestore during the `make install' step. | |
798 | ||
799 | 2. Linux port specific bugs added to the manual pages | |
800 | ||
801 | 3. Incorrect estimation of the number of tapes blocks fixed when doing | |
802 | incremental backups. | |
803 | ||
804 | 4. Better ls-like format in restore in interactive mode. |
